5.17g アルミニウム センターロック ローター ロックリング カバー | インナースプライン | Shimano SRAM

So beautiful finish !

These look great when paired wth the lightweight rotors and the matching cassette lock ring. The pair of lockrings weighed 11g versus the stock Ultegra at 16g.

When you are looking for a way to shave a few more precious grams from your ride, this is where you look. Weight was exactly as promised, the price isn't too bad and the quality of the machining is top notch. I'll definitely order another set.

Great parts light and beautifully manufactured.

These were super lightweight as advertised however they just arent durable if you have to remove and install frequently.
